„I liked him [Arthur Rubinstein] as a pianist. He was a good musician and had a fantastic repertoire. He never had a great technique, but certain things he played well. I heard him play some of the Chopin etudes, the easier ones with great panache and I told him I had never heard them played better. He said, "Do you mean it?"“
— Vladimir Horowitz American classical pianist and composer 1903 - 1989
and I said, "Yes, I do mean it."
